Hi all,
I was just running some test problems with scipy.sparse.linalg.cg and
thing seem work work out fine.
To compare preconditioners, I'd like to get more detailed information
about the convergence history, but I haven't been able to figure out
how to, e.g., get the number of performed iterations or the (relative)
residual for each of those steps. Compare this with
http://www.mathworks.com/help/techdoc/ref/pcg.html.
Any hints?
Cheers,
Nico
